    Very helpful thankyou. I changed and checked all the cables before, even tried running the dvd player through on its own without cable box and it was still playing up. Much appreciated.

Hi.

The TV looks faulty, just perform some test to ensure that the problem is not depending on cables or connected devices, then call Phone4U and report the problem. They will replace the TV immediately.

About the problem:

"The picture was intermediate at first, would be on for 30 minitues and then go black. This morning the tele light goes green but shows no sound or picture just a black screen."

The problem can be a faulty inverter, or a defective main controller board or PSU. The inverter is the device that supplies power to the backlight lamp system, and when it is faulty it is commonly causing this problem.
If you want to know more on the technical aspects you can read this short article that I wrote. The article explains how to test inverter, PSU and main board:How to test an LCD TV or monitor PSU and inverter.
In no case attempt disassembling or repairing the TV. This TV is covered with 15 days seller return or refund policy and with one year limited factory warranty.

Before ringing Phone4U, ensure that the problem is not the cable or a defective receiver box (if you are not using the internal receiver).

Leave the TV disconnected from power for about ten minutes. This will drain power completely, discharging PSU capacitors and sometimes fixing temporary faults.

Connect the TV back to power. If the TV has an internal tuner, test using only an external antenna connection, with no other cable or device attached.

If the TV has no internal tuner, test the TV using different devices and cables. For examples, test first connecting a DVD on HDMI, then using a receiver or a console on AV (the white, red and yellow) cables.

Once you are sure that the problem is not depending on connected units or cables, ring Phone4u and have the problem sorted by replacing the defective set.

Best regards.

Ginko.

    Hi.

    If you have already tested the TV, you will have no problem in getting it replaced by Phones4u.

    Thanks for the feedback.

    All the best.

Distorted picture on RCA LCD TV


I have the same tv. Had repair man come to my home in late april. Said it is the power convergence board. $225 for parts and labor I was told. Bad thing is part was supposed to arrive mid-may,then mid-june and now mid-july. He say's part is on back order. I'm actually going to contact RCA soon to find out if this is true. This seems to be a common problem with this particular T.V
